This paper presents the results of estimating how much electricity is currently used and would be used in future in China's urban household-sector. Conclusions are derived from an analysis of data obtained from a questionnaire survey recently conducted in 13 cities in China. Electricity used for various purposes in China's urban-households is evaluated, considering climate conditions specific to the target regions and the possession of end-use appliances. How much electricity could be saved in the future by improving the efficiency of end-use lighting equipment, room air-conditioners, refrigerators, and TV sets is estimated. It is demonstrated that about 28%, reduction could be achieved in the year of 2020 by means of improving the efficiency of these end-use appliances. (C) 2007 Published by Elsevier Ltd.
